An antenna of each double-pole double-throw relay is in electrical connection with a negative pole of a power source.Temperature sensors and pressure sensors are alternately mounted on the base, and an output end of a PLC controller is connected with the double-pole double-throw relays and the single-pole single-throw relays. A temperature sensor signal source is used for controlling the double-pole double-throw relays, and a pressure sensor signal source is used for controlling the double-pole double-throw relays. By the PLC controller for circuit on and off of the double-pole double-throw relays and the single-pole single-throw relays, human body wires are substituted by the temperature sensors and the pressure sensors, and accordingly safety of users is improved.
